14 E Canadian Arctic Expedition, 1913-18 
Family CARABIDAE. 
By H. G. Fall. 
Of the Carabidse collected by the Canadian Arctic Expedition, a repre- 
sentative lot of 206 specimens has been sent me for identification by Dr. C. Gordon 
Hewitt, Dominion Entomologist. The number of species in the lot is not 
large — about fifteen— but of some of them considerable series were evidentlj'- 
taken, only a part of which were submitted. 
The chief difficulty eticountered in determining any collection of Arctic 
Carabidse, centers in that complex of small Pterostichi belonging to the subgenus 
Cryobius, which constitute so characteristic a feature of the Carabid fauna 
of those regions. The species are numerous, but are still very imperfectly 
known and to a great extent opinionative, and are not satisfactorily determined 
in any American collection. Their identification therefore in the following 
list must for the present be regarded as tentative. 
Genus Carabus Linn. 
Carabus chamissonis Fisch. 
Langton bay (Franklin bay), Northwest Territories, summer, 1911, R. M. 
Anderson, collector, I9 ; cape Barrow, Coronation gulf. Northwest Territories, 
August 4, 1915, J. J. O'Neill, collector. Id', I9. 
Genus Elaphrus Fab. 
Elaphrus riparius var. gratiosus Mann. 
Teller, Alaska; July 31, 1913, F. Joliansen, collector, two examples in 
badly damaged condition. 
Genus Nebria Lat. 
A single female of this genus was collected which cannot well be referred 
to any species thus far recorded from the American continent. It seems in 
most respects nearest to ohliqua and suturalis, but, unlike them, has elytral 
interspaces 3.5.7. punctuate. It bears the label — Collinson point, Alaska, 
May 9, 1914, D. Jenness, collector. ^ 
Genus Pelophila. 
Pelophila eschscholtzii Mann. 
Teller, Alaska, July 29, 1913, F. Johansen, collector. A single specimen 
in poor condition. 
*This specimen was submitted to Dr. E. C. Van Dyke for examination and he believes that it is a 
black-legged variety oibifaria, the typical forms with red legs being found in the Lower Yukon Valley.
